Azrael is a angelic force of death, in mythology he doesn’t actually bring death he instead departs the soul after death.
Azrael isn’t really a fearful being, if you want to work with him go for it he’s a necromantic usher almost but if you want to wield the powers of Death totally then look into ‘The Reaper’.
He is the personification of death and will call the gods of death to your side.
